Let's divide 30872181 by 981
We want to figure out the number of times 30872181 can be divided by 981.

Moving on to step 1:
The number 981 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 981

Step 2:
30 divided by 981 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 981

Going ahead to step 3:
308 divided by 981 is 0 with a remainder of 308.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 308 leaves us with 308.
Include the next digit (7) from the dividend after 308, then repeat: 3087 / 981

Step 4:
981 can be fit into 3087 3 times, resulting in a remainder of 144.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 2943 from 3087 leaves us with 144.
Include the next digit (2) from the dividend after 144, then repeat: 1442 / 981

Step 5:
1442 divided by 981 is 1 with a remainder of 461.
The next digit of our result is 1. 
Result so far: 31.0
The remainder is 461 after subtracting 981 from 1442.
Take the next digit (1) from the dividend and append it to 461, then repeat: 4611 / 981

Step 6:
4611 divided by 981 is 4 with a remainder of 687.
Use 4 as the next digit of our solution. 
Result so far: 314.0
The remainder is 687 after subtracting 3924 from 4611.
Bring next digit (8) of the dividend behind the 687 and repeat the process: 6878 / 981

Moving on to step 7:
If we divide 6878 by 981, we get 7 and a remainder of 11.
The next digit of our result is 7. 
Result so far: 3147.0
If we subtract 6867 from 6878, we get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 981

Advancing to step 8:
If we divide 111 by 981, we get 0 and a remainder of 111.
The number 0 becomes the next digit in our result. 
Result so far: 31470.0
Subtract 0 from 111 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 9:
1110 divided by 981 is 1 with a remainder of 129.
Record the quotient 1 as the next digit in the result. 
Result so far: 31470.1
Subtracting 981 from 1110 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 10:
1290 divided by 981 is 1 with a remainder of 309.
The number 1 becomes the next digit in our result. 
Result so far: 31470.11
The remainder is 309 after subtracting 981 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

The final outcome is 31470.11, with a leftover of 0.309.
